Genesis 18:2-5

2And he lifted up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,

3And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:

4Let a little water, I pray you, be brought, and wash your feet, and rest yourselves under the tree:

5And I will bring a morsel of bread, and comfort ye your hearts; after that you shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.12
